When I try to send mms, it says that it is sent, but the person never gets it. I've seen that mms can't be sent while wifi is on, but I don't even use the wifi. I've also seen that people have had succes with changing the apn options via the mobile networks settings, but all that I can do on that screen is turn the 3g on/off. It hasn't even been a month since I bought this phone.
